Silent footsteps go

Railway sleepers made from recycled plastic conserve resources and reduce noise

PLASTICS off track – valuable commodities for material recycling

Profits instead of expenses, reusing materials instead of incineration

Rails and sleepers from all railway operations are generally completely replaced or overhauled.
There is great progress to be expected in the rail industry and the redevelopment requirements of rail sections.
Demolished or exchanged chief materials like steel from rails and rail joints, concrete from sleeper materials or ballastless tracks, wood from sleepers and ballast from the train and railway companies are currently in high demand.

Yet other materials, such as plastic and rubber parts of the superstructure, are also apprehended but are unfortunately merely provided by suppliers for compensation in incineration facilities. This is not in line with a cohesive raw material cycle of our time.

The Berlin-based company Plastic- Aufbereitungs- und Verwertungs- GmbH & Co KG, abbreviated as PAV, now offers material recycling of small plastic components.
The so-called angled guide plates made from fibre-reinforced polyamides are also of particular interest.
An example from Berlin: Some 40 tons of these materials were collected on the renovated rail section between Lehrter Bahnhof and the Jannowitzbrücke in 2014 alone.

In cooperation with a disposal logistics company the angled guide plates were acquired, separated from the rubber bases, pulverised, cleaned and fed back into the old plastics cycle.
PAV thus proves that recycling can be designed effectively. Compensation is paid to the supplier, meaning that the process bears no costs for the train or rail companies from the achieved profits. It is a win-win situation.

This procedure is in accordance with the proverbial circular economy, and is thus secure in the interests of the DB company, which is taking up the cause of circular economy.

Solutions for material utilisation of plastic dowels and old rubber components are also being researched recently.

RPT® I - News

Following the “bridge” RPT® made of recycled Synthetics (http://www.eba.bund.de/SharedDocs/Standardartikel/Zulassungen/Oberbau/Sonstiges/21.61izbo-013-2101-050(525_10-ZzB).html) the Federal Railway Authority (EBA) has now approved, for operational trials, the “track-bed” RPT® Railway Plastic Tie® http://www.eba.bund.de/SharedDocs/Standardartikel/Zulassungen/Oberbau/Schwellen/21.60-21izbo-017-2101-010(501_13-ZzB).html 

Interested rail infrastructure companies may request further information here.


RPT® II - News

The track-bed RPT® has passed the “VIBROGIR” trial conducted in the SNCF/RFF laboratory. The VIBROGIR is the supreme trial for French railway ties (here).

RPT® III - News

On 31.7.2013 the PAV ended a two-year ZIM-KF project (conducted with BMWi funding through AiF Projekt GmbH). The project was a joint initiative with KuZ – Kunststoffzentrum in Leipzig gGmbH –, the leading company in the field of synthetics analysis and research in eastern Germany. The project presided over the development and testing of a wide range of formulations for use in the manufacture of railway ties from recycled synthetics. www.kuz-leipzig.de

 


RPT® IV - News

On 1.8.2013 PAV and the SKZ-KFE gGmbH (Süddeutsches Kunststoffzentrum Würzburg) launched a two-year development project*), one task of which will be to test ties and materials to provide quality control for the manufacture of RPT® synthetic ties. The project will also study the suppression of sound propagation and assess the environmental impact of RPTs® compared to that of wood, concrete, steel and competing synthetic materials. www.skz.de

*)As part of KMU-innovativ: Ressourcen- und Energieeffizienz, the “RPT®-Bahnschwelle” Project - FKZ 033RK007A – is part-funded by BMBF via Jülich, the project’s organizing body.


RPT® V - News

By the end of 2013, in a partnership with the machine suppliers GRAEWE GmbH, the extruder manufacturer KOMAX GmbH and the “Think Blue” extrusion equipment manufacturer, PAV will have set up a small-scale manufacturing plant at NAFTEX GmbH’s Wiesmoor site for the production of ties from recycled synthetics. The federal government is funding this investment through its environmental innovation program (KfW/BMU).
